Artillery guns are supposedly going to have their accuracy reduced (larger aiming circle) so that, effectively, their accuracy stays the same as now -- but you won't have shots constantly hitting the "edge" of the circle anywhere near as much.

I'm seriously considering buying back the T28 Prot. now. I made some serious bank in that thing and with the buff in credits i could support a fleet of heavies with the money that is possible now.

The Tier 8 Tds are significantly cheaper to maintain than the Tier 9s so the balance goes way up in favor of making an overabundance of silver in a Tier 8 TD now. The Tier 8 big guns can hold their own with any tank on the battlefield so the extra percentage in credits and xp is going to have half of the players salivating and the other half (non TD players) raising holy hell.
